Flag Day is a celebration of the American flag that occurs each year on June 14, the anniversary of the flag’s official adoption.
What we know fondly as the “Stars and Stripes” was adopted by the Continental Congress as the official American flag on June 14, 1777, during the Revolutionary War. Colonial troops fought under many different flags with various symbols—rattlesnakes, pine trees, and eagles—and slogans—”Don’t Tread on Me,” “Liberty or Death,” and “Conquer or Die,” to name a few.
The Declaration of Independence made the adoption of an American flag necessary. Previously, each colony or special interest had its own flag.
On that 14th of June, Congress made the Flag Resolution of 1777, stating: “The flag of the United States shall be thirteen stripes, alternate red and white, with a union of thirteen stars of white on a blue field …” Official announcement of the new flag was not made until Sept. 3, 1777.
